resolve tests

[Deep plumbing] Find QL unit tests in given directories.

GitHub CodeQL is licensed on a per-user basis upon installation. You can use CodeQL only for certain tasks under the license restrictions. For more information, see "About the CodeQL CLI."

If you have a GitHub Advanced Security license, you can use CodeQL for automated analysis, continuous integration, and continuous delivery. For more information, see "About GitHub Advanced Security."

This content describes the most recent release of the CodeQL CLI. For more information about this release, see

To see details of the options available for this command in an earlier release, run the command with the --help option in your terminal.


codeql resolve tests <options>... -- <test|dir>...


[Deep plumbing] Find QL unit tests in given directories.

This plumbing command is responsible for expanding the command-line parameters of subcommands that run QL unit tests, to an actual list of individual .ql and .qlref files to execute.


Primary Options


Each argument is one of:

  • A .ql or .qlref file that defines a test to run.
  • A directory which will be searched recursively for tests to run.


[Advanced] Divide the test cases into M roughly equal-sized slices and process only the _N_th of them. This can be used for manual parallelization of the testing process.


[Advanced] Only use queries that can be strongly identified as tests. This mode tries to distinguish between .ql files that define unit tests and .ql files that are meant to be useful queries. This option is used by tools, such as IDEs, that need to identify all unit tests in a directory tree without depending on previous knowledge of how the files in it are arranged.

Within a QL pack whose qlpack.yml declares a tests directory, all .ql files in that directory are considered tests, and .ql files outside it are ignored. In a QL pack that doesn't declare a tests directory, a .ql file is identified as a test only if it has a corresponding .expected file.

For consistency, .qlref files are limited by the same rules as .ql files even though a .qlref file cannot really be a non-test.


Select output format, either text (default) or json.

Common options

-h, --help

Show this help text.


[Advanced] Give option to the JVM running the command.

(Beware that options containing spaces will not be handled correctly.)

-v, --verbose

Incrementally increase the number of progress messages printed.

-q, --quiet

Incrementally decrease the number of progress messages printed.


[Advanced] Explicitly set the verbosity level to one of errors, warnings, progress, progress+, progress++, progress+++. Overrides -v and -q.


[Advanced] Write detailed logs to one or more files in the given directory, with generated names that include timestamps and the name of the running subcommand.

(To write a log file with a name you have full control over, instead give --log-to-stderr and redirect stderr as desired.)


[Advanced] Controls the location of cached data on disk that will persist between several runs of the CLI, such as downloaded QL packs and compiled query plans. If not set explicitly, this defaults to a directory named .codeql in the user's home directory; it will be created if it doesn't already exist.

Available since v2.15.2.
